<p><P>PROBLEM TO BE SOLVED: To provide a powder molding device which is hardly affected by the shape of powder moldings and characteristics or the like of the powder molding device and capable of making deviation of density distribution of the powder molding small. <P>SOLUTION: The powder molding device 1 is provided with: a die 11 where a filling part A is formed; a lower punch 21; an upper punch 31; an upper ram 71 which moves the upper punch 31 forward and backward to the die 11; an inclination filling means for filling the material powder P by inclination; and a control part 80, and has a DDV type servo driving device D10 which connects between the upper punch 31 and the upper ram 71 and measures pressurizing force when the material powder P is pressurized, wherein the control part 80 is constituted so as to adjust density of the powder molding W based on the pressurizing force of the DDV type servo driving device D10. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
